What Causes Sudden Muscle Spasms And Tingling Sensation In The Hands?
Read below
Detailed Answer:
I read your question carefully and I understand your concern.
Judging from that description the first hypothesis would be that of a rheumatological condition like rheumatoid arthritis or lupus, which are commonly associated with this color changing manifestations.
The other possibility is that of a peripheral neuropathy like carpal tunnel syndrome which typically causes abnormal sensations in the fingers you describe. It can manifest alone or combined with the rheumatological conditions which I mentioned.
Another cause to be considered would be a metabolic issue such as electrolyte imbalance, in particular low calcium which may also manifest that way.
So I believe you should be seen by your primary doctor for the presence of other signs indicating rheumatological conditions and some routine blood tests for metabolic alterations (electrolyte panel, liver and kidney function, glucose, thyroid function) and rheumatological conditions (rheumatoid factor and antinuclear antibodies). A nerve conduction study test, which assesses for damage to peripheral nerves may also be scheduled.
I remain at your disposal for other questions.
